JDOM is an open source, java based library to parse XML document and it is typically java developer friendly API.
SAX Parser is an event-based parser for xml documents.
DOM stands for Document Object Model.
Yes! Using StAX parser, we can parse, modify and create a XML document.
StAX is a JAVA based API to parse XML document in a similar way as SAX parser does but StAX is a PULL API where as SAX is a PUSH API. It me in case of StAX parser, client application need to ask StAX parser to get information from XML whenever it needs but in case of SAX parser, client application is required to get information when SAX parser notifies the client application that information is available.
It is java optimized, it uses java collection like List and Arrays. It works with DOM and SAX APIs and combines the best of the two. It is of low memory footprint and is nearly as fast as SAX.
No! XPath parser is used to to navigate XML Document only. It is better to use DOM parser for creating XML.
No! Using SAX parser, we can only parse or modify a XML document.
Yes! Using DOM parser, we can parse, modify or create a XML document.
When you parse an XML document with a DOM4J parser, you get the flexibility to get back a tree structure that contains all of the elements of your document without impacting the memory footprint of the application. The DOM4J provides a variety of utility functions you can use to examine the contents and structure of the document in case document is well structured and its structure is known. DOM4J uses XPath expression to navigate through the XML document.
This interface specifies methods for creating an event.
XPath uses a path expression to select node or list of nodes from an xml document. Following is the list of useful paths and expression to select any node/ list of nodes from an xml document.
Expressions:
DOM stands for Document Object Model and it is an official recommendation of the World Wide Web Consortium (W3C). It defines an interface that enables programs to access and update the style, structure,and contents of XML documents. XML parsers that support the DOM implement that interface.
ContentHandler Interface specifies the callback methods that the SAX parser uses to notify an application program of the components of the XML document that it has seen.
DOM4J gives java developers flexibility and easy maintainablity of xml parsing code. It is light weight and quick API.
This interface specifies methods for creating an event:
The DOM4J defines several Java classes.
Here are the most common classes:
You should use a StAX parser when:
This class provide iterator of events which can be used to iterate over events as they occur while parsing the XML document
SAX stands for Simple API for XML.
The DOM is a common interface for manipulating document structures. One of its design goals is that Java code written for one DOM-compliant parser should run on any other DOM-compliant parser without changes.
Following are various types of parsers which are commonly used to parse XML documents:
You should use a DOM4J parser when:
Following are the disadvantages of XML usage:
This class provide iterator of events which can be used to iterate over events as they occur while parsing the XML document.
Following are the key components of XPath:
Attributes Interface specifies methods for processing the attributes connected to an element.
Yes! Using DOM4J parser, we can parse, modify and create a XML document.
When you are working with the DOM4J, there are several methods you'll use often:
When you parse an XML document with a DOM parser, you get back a tree structure that contains all of the elements of your document. The DOM provides a variety of functions you can use to examine the contents and structure of the document.

JDOM gives java developers flexibility and easy maintainablity of xml parsing code. It is light weight and quick API.
SAX (the Simple API for XML) is an event-based parser for xml documents.Unlike a DOM parser, a SAX parser creates no parse tree. SAX is a streaming interface for XML, which me that applications using SAX receive event notifications about the XML document being processed an element, and attribute, at a time in sequential order starting at the top of the document, and ending with the closing of the ROOT element.
Yes! StAX is a PULL API.
XML Parser provides way how to access or modify data present in an XML document. Java provides multiple options to parse XML document.
You should use a JDOM parser when:
When you are working with the JDOM, there are several methods you'll use often:
Parsing XML refers to going through XML document to access data or to modify data in one or other way.
You should use a DOM parser when:
Following are the advantages that XML provides:
Yes! Using JDOM parser, we can parse, modify and create a XML document.
When you are working with the DOM, there are several methods you'll use often:
XML stands for Extensible Markup Language.
You should use a SAX parser when:
The XPath is an official recommendation of the World Wide Web Consortium (W3C). It defines a language to find information in an XML file. It is used to traverse elements and attributes of an XML document. XPath provides various type of expressions which can be used to enquire relevant information from the XML document.
DOM4J is an open source, java based library to parse XML document and it is highly flexible, high-performance, and memory-efficient API. It is java optimized, it uses java collection like List and Arrays. It works with DOM, SAX, XPath and XSLT. It can parse large XML document with very low memory footprint.
